Methods of expressing concentration of a solution.

Answer 1

Methods of expressing concentration of a solution

The amount of solute in a solution can be expressed in terms of two systems of units :

1. Group A units specify the amount of solute in a given volume of solution, such as strength molarity, normality etc. 
2. Group B units specify the amount of solute for a given mass of solvent or solution, such as mass %, mole fraction, molality etc

• The advantage of Group A units is the ease of solution preparation and that of Group B units is the temperature independence.

In a given solution, let solute be represented by (1) and the solvent by (2)
